Lead-Acid Battery Safety: The Ultimate Guide
The electrolyte''s chemical reaction between the lead plates produces hydrogen and oxygen gases when charging a lead-acid battery. In a vented lead-acid battery, these gases escape the battery case and relieve excessive pressure. But when there''s no vent, these gasses build up and concentrate in the battery case.
How bad is it to undervoltage a 12-volt lead-acid battery?
$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.
